    (54) Method and apparatus for adaptive learning type general purpose image measurement and recognition


    (57) This invention is an adaptive learning type general purpose image measurement and recognition method which comprises the steps of extracting a large number of basic initial features which are invariance related to parallel displacement of an object to be caught in an image frame and which have additivity with respect to a screen, and performing statistical feature extraction having learning function used multivariate analysis methods based on the extracted initial features to thereby enable use for various types of measurement adaptively. Further, this invention relates toan adaptive learning type general purpose image measurement and recognition apparatus which comprises a pick-up means to pick up objects of measurement in two dimensions, an image cutting-out means which partially cuts video signals of said picked-up images, a window signal generating means which generates a window signal for designating a meausrment scope, a correlating means which computes Nth order autocorrelation of said cut-out data within the scopes of said window signal, a memory means which stores coefficients of said autocorrelation, and an arithmetic controlling means which controls said respetive means as well as calculates multivariate analysis based on said computed values to thereby enable use for various types of measurement adaptively.
